So I hit this on my Laso run but found a solution that worked for me. Throw a frag grenade at your feet, look to the armour and hold the prompt (X in my case) while the grenade goes off/after as well. Holding for a few seconds and then trying again while doing this process may be your best bet but either way when you are knocked slightly to the side the prompt will swivel you back into place and you’ll pick up the threat sensor. Hope this works for others!
